Kubelka Munk Theory

Constant Extraction

Determining the specific absorption and scattering properties of individual dyes requires measuring them on a standard substrate. Application of the kubelka munk theory allows a dyer to build a digital library of dye behaviors. These constants are then used to predict how a new mixture of dyes will look on the same fabric.

Color Matching

Predictions made using this model significantly reduce the time spent on manual shade matching. Because the kubelka munk theory accounts for the background reflectance of the undyed fiber, it can be used for both light and dark shades. It works best on thick, opaque materials where light does not pass through to the other side.

Formulations are calculated in seconds, allowing the mill to respond quickly to new fashion seasons.

Substrate Application

Variations in the fiber cross section or the yarn twist can change the scattering behavior and affect the accuracy of the model. Consistent fabric preparation is required for the theory to yield reliable results.
